The FBI and law enforcement partners with the Los Angeles County SheriffþÄôs Department, the Monterey Park Police Department, and the Manhattan Beach Police Department are seeking the publicþÄôs assistance in learning the identity of serial bank robbers known as the þÄúNew Hat Bandits,þÄù believed to be responsible for five bank robberies over the past six weeks in the cities of Rosemead, Monterey Park, and, most recently, Manhattan Beach.

Two men suspected in four Southland bank robberies since October were photographed Tuesday robbing a fifth bank in Manhattan Beach, and investigators are seeking the public’s help in identifying them.

Both suspects can be seen wearing baseball caps that appear new in surveillance footage from banks they robbed in Monterey Park, Rosemead and Manhattan Beach. The FBI dubbed them the “New Hat” robbers.

“We need the public to look at the photos and tell us if they recognize them,” FBI spokeswoman Laura Eimiller said. “Their M.O. is to go into the bank and ask for hundreds and fifties.”

On Tuesday, the suspects asked for more than usual when they robbed a Citibank branch at 2710 Sepulveda Blvd. at about 1:30 p.m. They handed a clerk a note demanding cash and told her they wanted $50,000. One wore a gray hooded sweatshirt with a red cap and the other had a black leather jacket with a camouflage-pattern hat.

“They tell the victims to ‘be calm’ and, in both Manhattan Beach robberies, they suggested to the victim-tellers that the bank was surrounded — an intimidation tactic,” Eimiller said. “They verbally asked for $50,000 but they did not get it. They were very insistent about receiving $50,000 and stayed for quite some time.”

The clerk did not have access to that amount of cash, Eimiller said, adding that the average take of a bank robber is $1,000.

The men were not seen carrying weapons in any of the robberies.

Both men were seen inside Pacific Alliance Bank at 8400 E. Valley Blvd. in Rosemead during their first robbery on Oct. 10, Eimiller said. But on Oct. 23, only one of the suspects was spotted demanding money inside Chase Bank at 459 S. Atlantic Blvd. in Monterey Park. On Nov. 4, the pair is alleged to have robbed Cathay Bank at 250 S. Atlantic Blvd. in Monterey Park. Only one of the men was present during a Nov. 22 robbery of U.S. Bank at 3300 N. Sepulveda Blvd. in Manhattan Beach.

Witnesses described seeing the men fleeing in a Lincoln Navigator. Both suspects are described as black males in their 30s, 5 feet 6 inches to 5 feet 8 inches tall and weighing 150 to 170 pounds.

Anyone with information about the robbers or their crimes is asked to contact the nearest FBI office or dial 9-1-1. More information can be found online at www.labankrobbers.org/.
